I don’t really see 5G solving rural broadband issues. You still need to lay backhaul line from the node Bs, and 5G requires more of them, so it’s not orders of magnitude cheaper than running cable to home.
A lot of rural areas have backbone just fine. It's the last mile that's the issue. You can find gigabit business internet basically anywhere.

> AR glasses for example, could totally upend all of this and require 5G low latency 5G "low latency": I'm not impressed with "1-2 ms" first hop latency; 0.1 ms should be achievable by now, surely. AR over networks: Maybe. But I think having more compute out on the edge nodes is going to deliver more for us in the long term than faster comms. Every extra millisecond in the rendering pipeline decreases the usability o…
Carmack famously quipped that "I can send an IP packet to Europe faster than I can send a pixel to the screen" [1]. For VR and AR to break through, they're going to have to be in a form factor that resembles normal glasses, and at a much higher render quality (4K+) than anything we've got now. That's almost certainly going to require rendering remotely Stadia / Xbox Cloud style, with some minimal local processing. [1…
> In defining V2X for 5G, Seo says the most challenging thing was to provide high data throughput, reliability, and low latency, both of which are essential for anything beyond the most basic communications. Seo explains that earlier standards typically deal with messages with hundreds of bytes that are expected to reach 90 percent of receivers in a 300-meter radius within a few hundred milliseconds. The 3GPP standar…
Say, in 10 years from 1985 to 1995, personal computer CPUs developed from 80286 @12MHz and 134k transistors to Pentium MMX @133MHZ and 3.3M transistors, with at least 100x improvement in integer performance alone, to say nothing about FPU and the vector unit (MMX). And another similar jump occurred in next 10 (well, 11) years when Intel unveiled the Core line of CPUs.

Be careful with expectations of "possible" vs. "practical". 5G for IoT devices is a big deal in remote field and some industrial settings where wi-fi is not an option. Two examples for you: I worked on a pilot project with a state government group that wanted remote monitoring of water levels in wetlands and ponds spread across a few hundred square miles of mostly-rural area. wi-fi obviously wasn't an option and gett…
Is it realistic to expect 5G coverage in rural wetlands? From what I understand, the range of a single 5G base station is significantly lower than 2/3/4G so they are having to install new cell sites in major towns and cities just for 5G coverage.

I don’t think even 5G is low latency enough for what you’re describing—not even close. Stadia works because it’s not VR, so they have some latency headroom. For good VR (Valve Index, etc), you get around 20ms for the entire rendering chain.

>Try using LTE in a large city’s central train station at a busy time and see how you get on. There was some ad campaign in Helsinki about two or three years ago telling people to do just this to compare carriers. Telia, Dna, and all the others worked just fine at rush hour at the central station with 50mbps+
Ah, but Finland considers internet access a human right.

But your case what enabled the emergence of mobile apps and associated markets was the apparition of affordable smartphones -that's what created a new ecosystem for tech and pseudotech companies to grow in. What new market is 5g enabling?
No, it's more than that. There was no YouTube in 2000. Web video for wired connections was shitty. MPEG-2 was the codec dujour. Progressive Networks/Real Networks was people's conception of online video. Netflix was shipping DVDs by snail mail. If the iPhone existed in 2000, there still couldn't have been a TikTok. AR glasses for example, could totally upend all of this and require 5G low latency, and fast accurate p…

Around 2000, I was working at OracleMobile, attened 3GPP/Mobile Congress/etc meetings, and there was a similar discussion around 3g. People were like "what's the killer app"? At the time, most phones were WML/WAP and Blackberry-like SMS/MMS/Email experiences. People speculated "maybe music or video", but it was all very vague, no one imagined the smartphone revolution that brought all of these services, like Uber. I'…
The latency sensitive thing is supposed to be smart cars and roads. 5G is all about displacing terrestrial cable and telco to homes. (And profiting off of the carve out regulations around wireless. Most other applications don’t really care about latency. If anything, we’ve used software to move lower latency applications like voice to crowded, latent and unreliable networks.

Graphics hardware keeps getting more powerful and cheaper though, I don't think cloud rendering is going to get more useful over time compared to just rendering on the phone and using cloud streaming for big assets.
5G doesnt seem like its enabling anything fundamentally new. The talk of any ”killer app” based on having more throughput or on these optimizations always feels like demand generation and slightly inauthentic. Are there any technologies enabled by these techniques that are not possible today?
